The moon phase shows that D. light reflected during the first quarter and third quarter moon phases appears equal because the sun, moon and Earth are at right angles.
<h3>What is a moon phase?</h3>
It should be noted that the <em>moon</em> phase simply means the portion of the moon that we can see from the Earth.
In this case, the light reflected during the first quarter and third quarter moon phases appears equal because the sun, moon and Earth are at right angles.

Average acceleration is how much the car increases (on average) per second. So, since it increases by 30 m/s in 8 s, then dividing 30 by 8 will give you an average acceleration of 3.75 m/s^2 (remember that acceleration is ever increasing, so the unit is s^2, not just s)
Hope this helps!
Answer:
Jill average velocity is 0
Jack average velocity is 0.159337
Jill average speed = 1.593372
Jack average speed = 1.434034
Explanation:
given data
long swimming pool = 25.0 m
9 lengths of the pool = 156.9 s ( 2 min and 36.9 s )
10 lengths = same time interval
to find out
average velocity and average speed
solution
we know that average velocity that is express as
average velocity = .....................1
Jill come back where she start
so here velocity will be = 0
and
Jack ends up on the other end of pool
so average velocity =
average velocity = 0.159337
now we get here average speed that is express as
average speed = .............2
jack speed = 9 ×
jack speed = 1.434034
and
Jill speed = 10 ×
Jill speed = 1.593372
Answer:
The <u>water vapor</u> will have the greatest entropy at the triple point
Explanation:
At the triple point of water, which has the properties of 0.0075°C temperature and 6.11657 mbar pressure, solid ice, liquid water and water vapor exist together in a location
According to Professor Stephen Lower on LibreTexts website entropy is a measure the extent to which thermal energy is shared and spread in a system
The change in entropy, ΔS = ΔH/T
The heat change in = 6.01 kJ/mol
The heat change in vaporization, = 45.05 kJ/mol
The heat change in sublimation, = 51.06 kJ/mol
Therefore, the entropy of the water vapor > The entropy of liquid water, > The entropy of the solid ice,
The portion with the highest entropy at the triple point is the water vapor
The water vapor will have the greatest entropy at the triple point
